TIRE-VALVE ATTACH ER.

SPECIFICATION forming part of Letters Patent No. 650,423, dated May 29, 1900.

' Application filed November 13, 1895. Serial No. 568,780. (N0 model-3 To all whom it may concern:

Be it known that I, GEORGE I-I. ESCHRADER, a citizen of the United States, residingin the city, county, and State of NewYork, have invented certain new and useful Improvements in Tire-Valve Attachers, of which the following is a specification.

This invention relates to valves for pneumatic tires and the like, and aims to provide an improved-article of manufacture by means of which tire-valves can readily be attached to their tires.

Heretofore in pneumatic tires it has been customary to provide a radial rubber tube or cot projecting through the valve-socket in the felly from the tire to the inner side and to fasten a pneumatic valve in this cot by a wire or other winding around the cot for pressing it against the exterior of the easing of the valve. 7 This winding has caused impairment of the cot, and experience has proved that in many instances leakage between the cot and valve-casing occurs. The main difficulty to be overcome in such constructions is the danger that the cot will be severed near the tire by the creeping of the latter around the felly, which it is found in practice almost impossible to avoid. Immediately any leakage occurs or the cot is severed the utility of the tire is either destroyed or so impaired as to renderits removal and repair necessary.

My present invention aims to provide means whereby creeping of the tire shall be prevented to any material extent and such creeping shall be impotent to impair the valve'and connections, an improved means for attaching or applying the valve to the tire, and an improved article comprising a valve and attacher which can be readily applied by any person to the tire.

To this end in carrying out the preferred form of my present improvements I provide a flexible disk-like attacher, substantially fiat, adapted to be cemented to the tire and.

having a perforation near its center adapted to receive a pneumatic valve, and I construct a combined valve and attacher, the valve being rigidly coupled to the middle portion of the attacher and adapted to pass through the valve-socket of the felly, and the attacher adapted to be cemented around the shoe of the valve to the tire, with the valve-conduit substantially in coincidence with the inlet to the tire, and I provide certain other features of improvement which will be hereinafter more fully set forth.

In the accompanying drawings,which illustrate the preferred embodiment of my invention, Figure l is a fragmentary side elevation of a bicycle-tire provided with my improve: ments, a fragment of the felly being shown in longitudinal section. Fig. 2 is a fragmentary plan view of a tire and my valve and attacher. Fig. 3 is a fragmentary axial section of the valve attachment applied to the tire. Fig. 4 is a plan view, and Fig. 5 an edge view, of the attacher-disk. Fig. 6 is a plan View, and Fig. 7 an edge view, of the packing-disk; and Fig. 8 is a fragmentary side elevation of the improved attachment, comprising the valve and attacher, before application to a tire.

Referring to the drawings, let A indicate the felly of a wheel; 13, a pneumatic tire carried on the outer face of the felly; O, a pneumatic valve for the tire; D, a valve-socket in the felly through which the valve passes, and E a nut screwing on the inner end of the valve and against the inner face of the felly for holding the valve in position.

The felly may be of any suitable construction, the tire may be any suitable pneumatic or like tire, that shown having a single tube o having an inlet-hole b opposite the valve, and the valve may be any usual or suitable pneumatic or other valve controlling egress from the interior of the tire. The valve shown consists of a tubular shell F, having an external screw-thread c traversed internally by a conduit cl and closed by a cap G, screwing on the end of the casing, and having a packing-washer e clamped over and closing the conduit d.

According to my invention an attacher H is provided for the valve. In its preferred form this is a disk, preferably of oblong or oval outline and of flexible material, having a central part f, adapted for attachment to the valve, an aperture 9, adapted to coincide with the conduit through the valve, and an outer part 2., adapted to fit and adhere to the outer face of thetire. This is preferably a pure-rubber disk normally flat and of uniform thickness and adapted to be cemented to the tire and make a leak-tight connection therewith all around its central part f, which latter part is adapted to receive and make a leak-tight connection with the valve.

By preference the attacher H is reinforced by a textile or other reinforcing layer Lwhich preferably is securely applied to the rear face of the disk, tightly adhering thereto, and has extensions I beyond the ends of the disk, ex tending longitudinally of the tire throughout any desired length and adapted tobece' mented or otherwise immovably connected thereto.

According to another feature of improvement 1 provide as a new article of manufacture a combined valve and attacher adapted to be applied to a tire by any person and simply requiring for such application the proper adhesion or cementing of the attacher to the outer face of the tire. The valve and attacher may be united in any suitable or desired manner; but I prefer to employ a separable connection between them, and especially to use the connection shown, wherein the valve is provided with any suitable character of projecting annular shoe or flange J on its end, which passes to the inner side of the disk H, being sprung through the hole g therethrough, while a nut K, having a corresponding wide clamping-face 11, screws on the valve-casing toward the disk H, clamping the latter in a leak-tight manner between itself and the shoe J. An antifriction thin metal or other suitable washer L is preferably in terposed between the nut K and disk II, and a'eompression packing-washer M is preferablyzinterposed between the shoe J and disk H, so that impairment of the latter is preventedand its distortion by rotation of the nut is avoided. The nut is preferably set up so tight as to make a permanent closed joint between the attacher and valve during all normal conditions and can only be released by using considerable force and a Wrench. The compression of the disk between the shoe and nut will not materially impair it, although it may give the disk a slight convexity on its tire side, which is not objectionable.

Preferably the valve-shell is constructed with a reduced smooth cylindrical neck j, extending from the shoe J to above the Worki-ngface of the nut K, and the washer M and disk H are sprung over and elastically embrace this neck, the hole 9 of the disk and the hole 7c of the washer being normally of the same or a smaller diameter than that of the neck. The shoe J is best formed on its upper face with an inner groove Z, a roughand the disposition of the groove between provisions for turning it may be substituted.

According to another feature of improvement the valve contacts with the felly in case of creeping and opposes its metallic exterior to the walls of the socket through the felly to prevent such creeping instead of opposing any part of the tire or attacher to such walls. Any construction by which the metal instead of the rubber shall perform this function may be employed; but I prefer to utilize a portion of the nut K for this purpose. To this end I provide the nut with a portion N, preferably a cylindrical inwardly-projecting head, between which and the body of the nut there is a groove a, which head substantially fits the valve-socket D in the felly and engages the walls of the socket, thus preventing movement when there is any tendency to creep. The force and the wear in overcoming this tendency is all applied to the head N, by which it is transmitted in part to the fastening-nut E at the inner side of the tire and in part to a large circular inner portion of the attacher H in such manner that the latter will not be impaired by the strain and can resist it.

In practice the attachment comprising the valve and attacher combined will be sold as an article of commerce, and the attacher can be caused to adhere to the tire by an ordinary cementing operation, which can be done by any person. Should it ever become necessary to remove the valve, the latter can be loosened from andthen sprung through the attacher and a new valve applied in its place. The attaching-disk will also be used by those who wish to apply other valves to it or to substitute a new disk for a worn one.

It will be seen that my invention provides improvements which can be readily availed of and which greatly simplify the application of tire-valves to the tires and remove the chief danger heretofore existing in the use of such valves. The danger of severing the cot heretofore employed has been so great that various expedients for strengthening it have been resorted tosuch as, for example, placing longitudinal resisting threads or cords along its tubular portion and near its face. These efforts, while involving much trouble and expense, have only served to somewhat prolong the life of the cot, none of them being sufficient to prevent its eventual impairment.

My improvement completely removes the danger to the valve connection heretofore incidcnt to the creeping of the tire.

It will be understood that the invention is not limited to the particular form, combination, or construction shown, but that it can be availed of according to any modifications desired without departing from the spirit of the invention.

What I claim is- 1. An attacher for tire-valves, comprising a rubber sheet H, and a textile reinforce I fixedly carried on the outer side thereof, and having extensions 1 extending beyond said part H, said sheet H and reinforce I both adapted to be connected to the outer face of a tire to connect a valve thereto.
